If you want to purchase a slurry pump in Australia, it is essential to know the different types of pumps you can choose from. Before talking about the different types of pumps you can use to pump slurry, we will look at some of the critical considerations before choosing the right pump for your application.
The nature of solids
It is important to consider the nature and size of the solids in the liquid you want to pump. This is because the size and nature of solids will affect the amount of wear on the pump and if the solids will pump through the pump without clogging it or causing damage.
The corrosiveness of the slurry
Another important thing to consider before choosing your pump is the corrosiveness of the slurry. Corrosive liquids will war the components of the pump and are likely to dictate the selection of the material of the pump you choose.
Slurry or sludge pumps are larger than standard pumps
Slurry or sludge pumps have more horsepower and are built with more rugged shafts and bearings. The centrifugal pump is the most common type of slurry pump. Centrifugal pumps move slurry using a rotating impeller. Centrifugal pumps that are optimised for pumping slurry come with larger impellers and feature thicker and fewer vanes on the impeller.
If you are pumping abrasive slurries then these types of pumps may be made from specialised high-wear alloys. Hardening steel is also another common option for pumping abrasive slurries. It is, therefore, important to tell your slurry pump company the nature of the slurry you are pumping to get the best pump for your needs.
For certain types of pumping conditions, positive displacement slurry or sludge pumps may be used. These conditions include a high head, a low slurry flow rate, a desire for greater efficiency, improved flow control and more.
Choosing and operating a sludge or slurry pump
Choosing the right pump for pumping slurry can be a complex and daunting task due to the balance of numerous factors including pressure, flow, abrasiveness, viscosity, particle type and particle size. An applications engineer should consider these factors and help you choose the best pump option for your application. When determining the best pump to use, it is important to follow the following steps.
The nature of the materials being pumped
It is important to consider the particle shape, size, and hardness of the material being pumped, the corrosiveness of the slurry, and the in-pump viscosity of the material.
The components of the pump
If you are using a centrifugal pump, you should ensure that the material used to make the impeller and the design of the material is appropriate for pumping slurries. It is also important to consider the chemical compatibility of the slurry with any present elastomers in the pump. After addressing both the components of different types of pumps and the nature of the slurry, you may choose the potential pump for your application. Make sure you buy your slurry pump Australia from a reputable vendor.
